Why Your Heart Attack Risk May Increase This Winter …
September 11, 2010
Cold weather may increase your risk of a heart attack, according to new research from the UK. Each 1.8 degree Fahrenheit reduction in temperature on a single day was linked to about 200 additional heart attacks.
The greatest risk came within two weeks of cold-weather exposure, and those aged 75-84, along with those with coronary heart disease, were most vulnerable to the temperature changes.
“Cold temperatures are known to raise blood pressure and also increase levels of certain proteins that could increase the risk for blood clots. Certain activities more commonly performed during cold weather, such as snow shoveling, might also contribute to the risk, the researchers say.”
